Running Average Formula/Function
Aug 22, 2006
I wonder if it is possible to formulate a formula in which average values are recalculated after every added record.
For example:
Record 1 shows an amount of 200 so the average value after 1 record is (200/1) 200. Record 2 shows an amount of 250 so the average value after 2 records is ((200+250)/2) 225. Record 3 shows an amount of 210 so the average value after 3 records is ((200+250+210)/3) 220.
I don't want to calculate all averages manually and most probably there must be a formula that is able to recalculate the average value after another record is added to the file.

Is there a way to include an if then else function to an average formula that will skip cells with zero?
I went into better detail in the attached example.

Actually with the help of array formula I"m taking out Average, Min, Max value of ranges and I was omitting zero but the problem is occurring that if i have originally zero in my ranges then Average & Minimum function is not working properly.

In the attached spreadsheet, I want to do a running average of the "To" column (column G) for each company throughout the 8 year period. The only problem is I want to do it with replacement based on column D, meaning if the same brokerage firm comes out with a new announcement, it will replace the value of the old one in the running average calculation.
Here is an illustration of what I mean:
Looking at Company A between row 2 and 12, the value for Consensus in row 2 should be the average of Column G in row 2, row 3 is the average of Column G in row 3...row 11 is the average of Column G in row 2 to row 11, but row 12 will be the average of Column G in row 2 to 12 be excluding column 5's value because both column 5 and 12 are issued by the same brokerage.
I want excel to replace new recommendations by brokerages over the old ones in the running average calculation.

building a spreadsheet to track instructors' classes' test scores. I have 3 basic variables: 1.) The instructor's name 2.) The course taught, and 3.) The classes' scores for that particular course. The 3 courses each have 3 different variations of the end-of-course test (9- total tests.) On the last page of the excel spreadsheet, I have a block for each of the instructors. I've been trying (with no success) to keep a running average of each instructor's class test average for the 3 courses. The part that is stumping me is associating the instructor's name with their class average, and then averaging all of their grades on that page together; the main reason being that this document is living, and new grades are entered almost daily. I tried using variations of the count function with no luck, other than to tell me how many times a particular instructor has tested in a particular test. Please help, I have the feeling that the function I am looking for is way-above my skill-level in Excel.

I need to do the following and can't figure it out. How do I create a running average that will only calculate the averages in % each month. Example: Opt 1 for Jan, Feb, Mar =1 each= 3 total = 100%; OPt 2 for Jan, Feb, Mar =1,0,1= 2 = 66%; Opt 3 for Jan, Feb, Mar = 0, 0, 1 = 1 total = 33%. My problems is I want monthly running average that shows the yearly percentage up to date but only for the months there is a value 1 or 0. How can this be done because the way I have it now, those % are being divided by 12 and that isn't the correct %

I have sales numbers which is in the form of a running total dollar amount and I would like to keep track of the average increase in dollars.
So basiclly if the Jan total is $100 in column a, the Feb total is $150 in column b, and the March total is $200 in column c. I would like a formula that will tell me that the average increase in dollars is $50.

TotHCInv.Value = WorksheetFunction. Sum(KRInv, PBLInv, CRInv, PVInv)
If i >= 34 Then CPSCtphRMA.Value = WorksheetFunction.Average("G" & (i - 30) & ":G" & i)
The first line runs properly, but the second line bugs out with the error message "Unable to get the Average property of the WorksheetFunction class". I can simply do the math, but I thought that using the worksheet function would be easier than summing and dividing. I'm curious, though, as to why I can't seem to use the Average function.

I have a vba function linked to conditional formatting that i want to temporarily stop while a sub to insert a line is running as the sub stops when it hits the sheet where the vba function operates. When i disable the vba function (or remove the vba function) the sub works fine, if the vba function is not disabled the sub stops.

TPR, DISPLAY and FEATURE columns generate a rating based off of an IF function. In the Executed column, I need TPR, FEATURE, DISPLAY to be averaged together...BUT....In I want the average only include columns where there are numbers. For example in row one the eqn would be (1+3+2)/3, but in row 2 the eqn would be (1+1)/2...can I state an average function within an if function? Or what would be the best way to create an eqn for this?? I have thousands of rows to complete and doing it manually is not an option.

I'm using the formula =AVERAGE(B16:L16) to give me the average.
However I have a couple of problems with this. Firstly I would like to exclude the value zero from the average. Secondly to also ignore the lowest and highest values.
Example, if the values in the cells are 0,1,2,3,4,5,6,7,8,9,10 then the current result shows 5, by ignoring the 0 and lowest value 1 and highest value 10 the average should be 4.5.

I have a piece of code that hides unneeded rows, it does work but it is very slow.
This is in the worksheet part of the project. My problem is as it runs it "jumps" in to a function I have in a module that counts continuous rows. I would like to know why it is doing this and what I need to do to stop it? I have another piece of code that is structered exactly the same that hides unneeded columns and I do not have any problems with that. I know both pieces of code are dealing with rows and I think this is part of the problem but I can not see any reason why the first bit would call the second bit?
Dim C
With Worksheets("CEN OAS"). Range("D5:D378")
.EntireRow.Hidden = False
End With
For Each C In Worksheets("CEN OAS").Range("D5:D378")
If C.Value = "" Then
C.EntireRow.Hidden = True
End If
Next C
Function to count used rows....................

I am trying to create a table showing the yearly average occupancy rates per quarter for every year between may 1998 and december 2008 inclusive (for licensed hotels, motels and guest houses, and serviced apartments in Australia; if that interests you).
I have a spreadsheet with a row of data showing the appropriate quarterly results for those dates. Let's say the data for this is displayed A1 through to A44.
For the yearly per quarter averages, let's say they are to go from B1 through to B11, I know I could put, for each year, an average formula with the relevant data range. Finding this to be tedious, I tried to fill-down.
I learnt the hard way however (not being too aware of how excel's grammar ticks) that the fill down function will not work for me. i.e., if B1 contained the average for the data range A1:A4 (the four quarters of 1998), the filled-in B2 would have the data range A2:A5 (i.e. the 2nd quarter of 1998 through to the 3rd quarter of 1999).

I have a data range - C4:C54 and I want an AVERAGE calculated in C56, but I only want a value displayed in C56 when a data entry is put in. Up to 50 data points could be put in anywhere e.g. only 14 values in C16:C30, or 44 values in C6:C50, or the full 50 in C4:C54.
The formula I've been trying is
=IF(ISERROR(C4:C54<>""),AVERAGE(C41:C54),"")
However, when no values are in the range it displays DIV/0! whereas I'd like the cell blank.

How do I perform average for a range and be able to exclude outliers. For example I am taking 100 measurements, some are not measureable and recorded as 9999.9. How do I average 100 values, but exclude all the 9999.9?

Each sheet contains the test data for an individual class and I am trying to create a "Totals" sheet where I can show the average that each class had on a particular test and the letter grade breakdown. I am trying to create one 'average' formula that I may then copy across that will change the sheet reference automatically without me having to manually re-create the formula every time I add a new class sheet. I tried using the INDIRECT function but could not get it to work. Keep getting #Ref error.

I will attempt to make this as easy as possible in explaining something I am looking to do. I am looking to Calculate the average lifespan of an individual based upon
1) They are "dead" (A status,either "Alive" or "Dead" found in Data!F2:F653)
2) They were born between 1/1/2007 and 12/31/2007 (Delivery Date provided in Data!C2:C653)
The lifespans were provided on Data!E2:E653

I have data in Column A as follows:
A1 15
A2
A3 20
A4 56
A5 45
A6
A7 71
A8
A9 23
where cells A2, A6 and A8 are empty.
I want to be able to AVERAGE or SUM the first four nonblank cells. I know I could manually select the cells, but I have a spreadsheet with 30 columns and 40 rows, and the data (including empty cells) in each column is different.
Is there a single formula that will find the first four nonblank cells and then perform the AVERAGE or SUM function?

I'm trying to find the best Macro or Formula to get this done.
Sheet 1 has a list of salesperson in column "A" and the total numbers they made on Monday (in the same row, column "E"), Tuesday (In the same row, column "F"), Wednesday (In the same row, column "G"), Thurday (In the same row, column "H"), and Friday (In the same row, column "I"). I also have a sheet for each individual salesperson. I need to find a Macro or a Formula that I can use to give me the average of the numbers if "A5" = the salesperson in Sheet 3 then avarage the numbers from "E5" to "I5" and I want the results to show up in cell "D35".

I need some assistance in using an array formula which averages based on multiple arguments. The relevent range names in my input data are:
Col A - Manager Col B - Report Type Col C - Days taken to Complete
and I have used Validation Lists to include several different Managers and 5 Report Types which I'll call A - E, with Days taken to Complete an input. Each Manager may have 0 to numerous instances of each report during each period.
I'm trying to build a table which includes each manager and the average number of days taken to complete each report. The complication is that, while Report A & B are separate reports, for this purpose I need to get an average for A & B together.
For C, D & E, I have used the following:
{=AVERAGE(IF((Type="C")*(Manager="Smith"),Days_taken_to_Complete))}
For A&B, I have tried:
{=AVERAGE(IF((Type="A")*(Type="B")*(Manager="Smith"),Days_taken_to_Complete))}
but this doesn't work. Could someone please advise me the correct formula if either of two states in a named range are to be used to average a second named range?

I am working with averages of ACT scores and Class rank percentages. I cannot figure out how to exclude all the zeros and/or DNR (do not rank) values that are in those columns. For example if I have 10 items, and 2 are DNR, the I want to exclude the 2 DNR's in my average. I tried putting it in the Row or Column area and unchecking what I wanted to exclude and then drag it into the data area, but that didn't work either.

I have a spreadsheet that contains developer related data. I want to be able to do a weekly analysis of average construction time and costs. The problem I am running into is properties enter rehab phase and exit rehab phase throughout the week.
For example:
I want to know the average $ spent and total rehab time week 1 of april. I may have 4 homes that entered rehab that week and 3 that move out of rehab that week. Moreover, I need to ensure those homes that entered and are still in rehab for that week are counted. How do I accomplish this feat?

I am working on an excel master marksheet which will be distributed to many teachers to fill in their students marks. How can I enter an average function that can work out the mean for those different classes. For example I'd like the main average function to be like this =average(d5:d50) but if a teacher has thirty students in his list the mean will be only limited to the marks of those thirty students. Same thing I want for the mode function and the median function.

This time I have a situation like this:
Column A - Dates
Column B - Equipment Type
Column C - Load Start Time
Column D - Load End Time
I need to do some statistical analysis (average, mode, medium, st dev) on the load times, which is load start time - load end time. As far as I know, I can't subtract ranges (column d i column c) within Averageifs function. I assume I would need to use an array function for this.
